Hollow interlayer steel pipe confined concrete column, concrete beam joint and building structure
The invention discloses a hollow interlayer steel pipe confined concrete column, a concrete beam joint and a building structure. According to the building structure, the hollow interlayer steel pipe confined concrete column and a reinforced concrete beam are crossed in a concrete beam joint structure; the outer steel pipe of the hollow interlayer steel pipe confined concrete column is broken near the joint core area formed by the intersection of the outer steel pipe and the reinforced concrete beam to form the broken part, so that the phenomenon that the outer steel pipe is bent due to the action of a large vertical load can be effectively avoided, and the outer steel pipe only has a restraining effect on concrete; the bearing capacity and the ductility of the hollow interlayer steel pipe confined concrete column are greatly improved; the end stress increasing portion of the hollow interlayer steel pipe confined concrete column is reinforced through the column end vertical stiffening ribs, and the joint area vertical stiffening ribs and the annular plates are arranged in the joint core area, so that local buckling of the inner steel pipe under the large load effect can be effectively avoided, and meanwhile the functions of a strong joint and a weak component are achieved.
本发明公开了中空夹层钢管约束混凝土柱、混凝土梁节点及建筑结构，本方案建筑结构在混凝土梁节点结构中采用中空夹层钢管约束混凝土柱和钢筋混凝土梁交叉的形式，通过中空夹层钢管约束混凝土柱的外钢管在其与所述钢筋混凝土梁交叉形成的节点核心区附近断开形成断开部，能够有效避免了外钢管受到较大竖向荷载作用而发生屈曲现象，使得外钢管只是对混凝土起约束作用，令中空夹层钢管约束混凝土柱的承载力和延性大大提高；而中空夹层钢管约束混凝土柱的端部受力加大部位采用了柱端竖向加劲肋进行加强，并在节点核心区设置了节点区竖向加劲肋和环板，使其能够有效避免内钢管在较大荷载作用下的局部屈曲，同时起到强节点弱构件的作用。
